ERICO - Cadweld® Welded Electrical Connections


Connections are often the weak point in ground circuits, especially if they are subjected to high currents and corrosion. The capacity of a grounding circuit to protect property and personnel depends on the quality of it’s connections.

Only the CADWELD exothermic system can provide the permanent, low-resistance connection needed to create a long-lasting, reliable grounding network.


  • Current carrying (fusing) capacity equal to that of the conductor
  • Will not deteriorate with age
  • Permanent molecular bond that cannot loosen or corrode
  • Will withstand repeated faults
  • Low labor costs
  • Made with inexpensive, lightweight and portable equipment
  • No special skills are required
  • No external power or heat required
  • Can be checked for quality by visual inspection

Exothermic Welded Connections

The Cadweld Connection.
Simple - Fast - No gas or arc welding

Cadweld is a true fusion, or molecular weld of virtually
pure copper for:

• Electrical systems earthing
• The earthing of heavy duty industrial equipment
• The cathodic protection of plant installations
• Busbar connections
• Electric transport and communications systems
• Cadweld is self-contained
• No arc welding equipment
• No gas cylinders
• No external power source.
